Since your husband has diabetes, is overweight, and has a chest scan score of 9, his body is fighting a significant infection. First, please use cool, damp cloths on his forehead and underarms (tepid sponging) to help gently lower his temperature. Ensure he drinks plenty of fluids and monitor his blood sugar closely, as fever can affect it. Since he is already taking Paracetamol 650 mg along with his other medications like Zukanorm M, do not give extra doses without advice. Please contact his treating doctor immediately or seek emergency medical care for a prompt re-evaluation of his treatment plan.
